The service was fine, about the same as you get on most lower end airlines. I dont understand the perks of flying them much anymore for the cost.

The service was fine, about the same as you get on most lower end airlines. I dont understand the perks of flying them much anymore for the cost.

the flight was significantly delayed. Not much was done by the airline to compensate passengers

the flight itself was totally fine. The crew were great and very helpful. The flight was delayed, however, over an hour without a lot of information as to why.

Had to walk back and forth between concourses to figure out which gate I was supposed to be at. The app and the flight board in the airport had different gates listed. Was told numerous times to check bags only to get on the plane and find that there was plenty of room for bags. The flight was over an hour late which had me landing after the last train departed. WiFi was unusable

My experience was okay I changed my returning flight and I was charged extra money which I dont think should be the case, especially because I experienced small delays from my going flight. And many flights were either canceled or delayed after my original flight time. I believe some customers should have the ability to change flights due to certain situations

I've taken four flights with Southwest within the last three months and every single flight was delayed.

It was great and arrived home a little sooner than expected which is nice.

I fly out every other weekend and this is the 4th time my flight has been delayed at Southwest. I will be flying out twice a month on average for the next 6-7 months. If this is your average ‘on time’ I’ll probably be flying another airline.

WiFi was inoperable - second in four recent Southwest flights where that was true. I need WiFi for work and if Southwest cannot provide, I’ll stop using it

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

I enjoyed the whole flight and the crew was amazing i dont usually fly delta

Very nice the whole crew was amazing and very professional. I had an offer for a drink it was handled great and amazing crew and nice flight.

I just wish the boarding process/time to take off after boarding was quicker and more efficient. I also wish that the overhead luggage was managed better. almost every time i fly there is no space for carry ons and they are either checked or I end up having to store it several rows back from my seat. Delta should not offer carryons for all customers if there is not actually space for everyone

Boarding was delayed by an hour and then we proceeded to sit on the tarmac for another 30-40 minutes. No clear explanation was ever given and the delay caused me to miss my connecting flight home. Was forced to stay the night in the connecting city which impacted my following workday and cause personal issues at home as well.

I didn't like like much about my experience with Delta. I had to spend the entire day at the airport due to some mechanical issues. My flight was supposed to leave at 8:30am didn't leave until 6pm. Horrible experience.

Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Seats needs to be wirer and food is very poor

Seats are uncomfortable and left me in pain in my tailbone area. I got about one hour of sleep.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

Both my flight where delayed Had 25min to make it to my transfer flight

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

Mostly good, flight take off in time and land earlier I can’t ask for more..

The crew was not nice this time. I asked for a drink one time and the girl didn’t say anything to me and just got me the hot drink while walking super fast to the back. We were sitting in the back and she wasn’t doing anything except socializing. She was upset I asked for something and she had to do her job. I also didn’t fully have it in my hands when she handed it to me so it was dangerous. She was abrupt and rude. She wouldn’t allow for people to spread out like previous flights we had been on if they were empty, and there were empty rows. It was strange and she enjoyed being angry at us.

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Everything was great the only issue was lack of Wi-Fi

What's not to like? Value?definitely. Every JetBlue member was extremely friendly on this flight. Very very nice new-ish aircraft,plenty of room. GOOD coffee. Entertainment,I didn't need it,but I think its available. What to do better? Well,there's nothing we can do about the other people, unbelievable how some folks are operating. Just don't allow people to lug all their stuff onto the aircraft. 1 bag. That's it. Be easier for you too. I personally would enjoy more options in schedule. One flight in and out a day is warranted given the local,I understand, but the times are inconvenient. Again, I completely understand why it is that way,It would however be great to have different options.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.

The flight departed more than 1 hour late. Leg room is bigger than most airlines

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Ultimately fine but plane seemed dated and creaky and landing was hard…. At no time did I feel unsafe so thank you.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
